So im wondering if a topshift doubled with 4.7's on a local forum For a older yota truck will be able to fit into my truck. I did some searching for the adaptors i would need to make it work with my tacoma 3.4/5spd. Im still pretty confused on what im looking for lol.

If you have 23 spline gears, select none for gears, and just select whatever transmission adapter you need. Total price should be 1150 in your cart +Shipping.

That's all you need unless you need 23 spline gears.

Sorry i was including what the doubler for the hilux is posted at. and yea i would need 23's. so that would but it at roughly the same as buying a built one haha.

I need to find a used one. Whens the price gunna drop lol the hilux ones are getting to be dirt cheap.

Seeing as how the taco 5spd is the same tranny as the one of the jeep tj trannys (ax15 i thinki) with just a different pattern has anyone ever managed to swap a rubicon tcase or a terrlow kit into one of these somehow. My research turned up nothing but who knows:confused:

Hmm cricket:p
Iv searched but came up empty
The only real possibilty to get a better case for less coin than i found is the Dana 300. I figure i can do it for around 1400 out the door. Once again i can't find anyone in a stockish IFS tacoma running one. Anyone know just how much of my floor i would have to chop out to fit one of these things? It looks pretty simple to actually convert one to driver drop. On top of that these things are bomb proof. Atlas cases are built off of them even my buddys 38 foot 4wd camper runs one. however the problem is i can only get it with 4.1 gearing in the stock housing.

From the r151 to this.

From the gear reduction case

To Dana 300.

I found this thread pretty interesting but a little more technical than i think i can pull off on my own. But pretty sick that it will leave the front output in the same ballpark as stock with a doubler.

Got this answer on another forum Figured i would post this here aswell for bordom reading pleasure. Im going to start collecting a dana 300 and the other non spendy adapter parts may take me awhile to actually stick it in the truck:lmao:

Mike

the dana 300 is cast iron, gear driven, heavily supported for low range gears, shifter cables, clocking adapters, etc. its very compact with fixed output yokes front and rear that are cheaply upgraded to 1330 joints using JY parts. it uses twin shift rails that can function independantly, meaning one rail controls the front output and one controls the rear, H-N-L on each stick so you can choose from RWD High and low, FWD high and low, and 4wd high and low. stock low gear is 2.62:1

the np231 is aluminum cased, chain driven with a 2.72:1 planetary reduction section in the front. its either in high or low, and 4wd or rear wheel drive. no front drive option, no rear low option. it also incorporates the slip yoke into the tailhousing rather than driveshaft so theres a very long tailhousing on the back of the unit that just sucks. you will need to cough up $100 -$250 for a slip yoke eliminator which cuts this down, replaces the tailshaft housing and attaches a stubby fixed yoke. 231's arent bad units if its already in your truck, but id never suggest swapping to it. they do make a good crawl box in front of the Dana 300, but again, only if it bolts to your current transmission. the dana is what gives you all the options.

NWF makes a cable shifter for the dana 300 that will allow it to go just about anywhere. . someone on NEOW actually has one for sale.

problem with the OTT setup is you still have to adapt a minitruck gear driven crawl box to the back of your taco transmission, which requires a spendy adapter. so you'd be buying 2 tcase and 2 adapters.

you should be able to bolt a jeep AX15 5speed to the back of your 3.4 using an R150 bell housing from the 3.0 toyota with the jeep clutch and toy flywheel/pressureplate. that would allow you to run a box 4 rocks directly on the ax15. they're made by D.D. Machine and mate the np231 planetary box to the D300. if thats not deep enough, you can still go 4:1 in the D300 for ultra low.

if it were me, i would sell off the manual transmission, pedals, shifters, tcase, etc and acquire a toyota 3.4L automatic flexplate and torque convertor, R150 bellhousing, 92+ AW4 (23spline with a .500 stickout) transmission for $150 or less, control it without any computer at all using the rory desjardin rail shifter for $100 and then run the dana 300. auto wheels so smooth. theres no adapters and selling your current manual parts would probably leave you with money in your pocket.
